Haibo Chen commented on YARN-7933:
----------------------------------

[~rohithsharma] There is TODO comment in TimelineCollector.putDomain() "TODO If 
domain exist then check access for domain from aclManager"

Trying to understand this. Isn't  it the case that a TimelineClient must be 
able to authenticate with the TimelineCollector first before it can post data 
to that TimelineCollector? It seems to me that TimelineClient always owns the 
data that we allow them to write, including timelinedomain, hence we don't need 
to check ACLs any more.
